In addition to "Budd film", chrome-plated glass or dimming filter labeled ND 100000 is also a good choice. Both filters need to be placed in front of the lens. The use of sunglasses and low-power reduction lenses can not effectively reduce the light.

Shooting with Budd film can reduce the light and harmful radiation without reducing the contrast of the subject. That is to say, using Budd film as a solar filter can get better picture quality and even record the sunspot activity on the surface of the sun easily.

Extended data

When observing solar activities and eclipses, as well as taking photos of the sun, the traditional method is to use neutral gray filter, but now using Budd's solar observation protective film can filter light more conveniently, effectively and with higher performance.

5.0 Bader film can effectively filter out the brightness of 40W incandescent bulbs. Through the 5.0 Budd film, you can clearly see that the bright silk of this light bulb is like hair. The Budd film of 3.8 can't effectively filter out all the brightness of 40W incandescent bulbs, but through the film of 3.8, we can not only see the filament of the bulb, but also see the outline of the bulb.

When the sun is normal brightness, 3.8 Budd film is very dazzling in vision, and you can't see the details of the sun, but it is very suitable for taking pictures. Instead, it is 5.0 Bader film, which is suitable for visual observation and can also be used for taking pictures, but the non-exposure time is slightly longer.
